5. Setup and Installation
- Mounting the Servo: Secure the servo motor to your model's chassis or mounting point using the provided screws. Ensure it is firmly attached to prevent movement during operation.
- Attaching the Servo Horn: Select the appropriate servo horn for your application. The metal 25T horn offers maximum durability. Attach the chosen horn to the servo output shaft. Ensure the horn is centered before tightening the small screw that secures it to the shaft.
- Connecting to Receiver/Controller: The servo has a standard 3-wire connector:
- Brown/Black Wire: Ground (GND)
- Red Wire: Power (VCC, 4.8V-8.4V)
- Orange/Yellow/White Wire: Signal (PWM)
- Power Supply: Connect your power source (e.g., battery pack) to your receiver/controller, ensuring it can provide sufficient current for the servo, especially under load.

6. Operating Instructions
The Miuzei 25KG Digital Servo Motor operates based on a Pulse Width Modulation (PWM) signal from your RC receiver or microcontroller. The pulse width determines the angular position of the servo arm.
- Standard Operation: A typical PWM signal for a 180° servo ranges from 500µs to 2500µs, with 1500µs usually representing the center position.
- Control Range: The servo is designed for a 180° control angle. Ensure your control signals are within this range to prevent mechanical stress or damage.
- Initial Test: Before full operation, perform a low-power test to confirm correct wiring and functionality. Move the servo arm slowly through its range of motion.
- Application Examples: This servo is suitable for steering in RC cars, controlling robotic arms, or actuating surfaces in model airplanes and boats.

7. Maintenance
- Cleaning: Keep the servo free from dust, dirt, and debris. Use a soft, dry cloth for cleaning. Avoid using solvents or harsh chemicals.
- Inspection: Regularly inspect the servo wires for any signs of wear, cuts, or loose connections. Check the servo horn and mounting screws for tightness.
- Gear Lubrication: The metal gears are pre-lubricated. If the servo is disassembled for advanced maintenance (not recommended for average users), use appropriate servo gear grease.
- Storage: Store the servo in a dry, cool environment away from direct sunlight and extreme temperatures.

8. Troubleshooting
If you encounter issues with your Miuzei 25KG Digital Servo Motor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Servo does not move | Incorrect wiring Insufficient power supply No signal from controller Damaged servo | Check all wire connections for correct polarity and secure fit. Ensure power supply voltage is within 4.8V-8.4V and can deliver enough current. Verify your controller is sending a valid PWM signal. If all else fails, the servo may be damaged and require replacement. |
| Servo moves erratically or jitters | Poor signal quality Power supply fluctuations Mechanical binding Interference | Check signal wire for damage or loose connections. Ensure signal source is stable. Use a stable power supply. Consider a capacitor across the power lines if fluctuations are suspected. Ensure the servo arm and connected linkages move freely without obstruction. Keep servo wires away from high-current wires or sources of electromagnetic interference. |
| Servo overheats | Continuous overload Insufficient ventilation Internal short circuit | Reduce the load on the servo. Avoid continuous stalling. Ensure the servo has adequate airflow, especially in enclosed spaces. Discontinue use immediately and contact support if overheating persists without load. |
| Loss of precision or excessive play | Worn gears Loose servo horn | Over time, gears can wear. Replacement may be necessary. Tighten the screw securing the servo horn to the shaft. |
